Spring formal wear

Invited to a "formal" party in springtime? What to wear?!

Let's look in the closet....

- Long floor-sweeping evening dress?  none.

- Flowing Grecian style dress as seen on red carpets? none.

- Sequin dress? ....eh, too Christmas-y.

- Little black dress? ...eh, length too short, too cocktail.

- Maybe spring pastel-colored dress? none.

- Satin dress?  yes! I have two! halter blue one is...yuck, awkward midi length...needs to be altered.....which leaves the emerald dress....last styled for Petite Fashion Challenge #4 back in 2010 for Christmas party:

So this is the fanciest evening dress I own that fits :(

 Luckily, "emerald" is color of the year :)

Just need more colorful accessories...but definitely avoid gold, red, and black (winter holiday colors).

All I could find is my blue Forever21 Sparkling Teardrop necklace (reviewed here) 

Any other ideas how I should style an emerald dress for springtime formal event?
Oh, great suggestion! Floral heels...like these pretty Manolo Blahnik 'BB' Pump...swoon!
